Place cod on a shallow bowl. Sprinkle salt, pepper, and ginger all over the cod. Place sliced kimchi on the top.
Prepare a steamer with about 1 inch of water over medium high heat. Bring water to a boil.
Place the dish with the fish in the steamer. Cover, reduce heat to medium, and allow fish to steam for 10 minutes. When cod is done, it should flake easily.
Place minced garlic and vegetable oil in a small microwave safe bowl. Microwave on high for 1 minute 50 seconds. Remove and mix in soy sauce. Set aside.
Remove fish from the steamer when done. Cod should flake easily when cooked. Spoon off some of the juices if there is too much in the dish.
Drizzle prepared soy sauce and garlic oil dressing over the fish. Garnish with sliced green onions and cilantro.
